ADJUSTABLE FILE-DRIVER.

To all whom it may concern:

Be it known that I, TUNIS W. LOVELESS, of Corning, in the county of Steuben and State of New York, have invented a new and useful Improvement in PileDrivers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a central side sectional elevation of a pile driver constructed according to my improvement. Fig. 2, is a front elevation of ditto.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in a novel construction of the machine as hereinafter fully shown and described, whereby the monkey guides may be adjusted in a vertical position in case the ground on which the machine rests is not horizontal, thereby allowing the machine to be expeditiously applied to its work without the trouble of grading. The invention is chiefly designed for driving small piles, fence posts and the like, but it may be used for heavier work if constructed of proper size.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, B, represent two axles each being provided with wheels C. To the axle A, a frame D, is attached. This frame is formed of two parallel bars a, a, connected at their outer ends by a cross bar 5. To the other axle B, a similar frame E, is attached, and these two frames are connected by pivots c, as shown clearly in Fig. 1.

To the back end of the frame D, a curved or segment perforated plate F, is attached. The perforations in this plate receive a pin (Z, which is attached to a lever G, on the back part of the frame E, the pin (l, work ing in a crosspiece e, of the frame E, see Fig. 1.

To the front end of the frame D, a bolster H, is attached, said bolster being attached to the frame by a link f, the lower end of which is firmly secured in the frame D, and the upper end fitted loosely in the under side of the bolster, through which and the link f, a pin or bolt 7, passes. The upper part of the frame D, directly underneath the bolster is inclined downward at each side of its center to allow the bolster to be tilted either to the right or left. This will be understood by referring to Fig. 2.

To the bolster H, two longitudinal bars h, 72., are attached. These bars extend back some distance over the frame D, and their back ends are connected by a crosspiece 2', which is attached by a link 7' to a double in clined strip is, attached to frame D.

I, I, represent two vertical bars which form the monkey guides. The lower ends of these bars are attached to the front ends of the bars h, h, and the guides are braced from the bars 71., h, and bolster H, as shown at Z, m.

J, J, represent two upright racks, the lower ends of which are pivoted in the axle A, as shown at n, n. The racks J, J, pass through mortises in the bolster, one at each side of its center, and in each mortise a serrated plate 0, is secured, see Fig. 2. To the upper end of one rack J, a bar K, is pivoted, and the opposite end of this bar is slotted so that it may be fitted over the top of the other rack J, which is notched at its outer edge, said bar K, serving the office of a clamp.

The monkey is fitted between the guides I, I, and may be raised by a Windlass L, arranged in the usual or any proper way.

From the above description it will be seen that in case the wheels C, are on uneven ground, the guides I, I, may be adjusted in a perfectly vertical position, for instance, if the back wheels 0, are lower than the front ones, as shown in Fig. 1, the back end of the frame D, is elevated to a horizontal position by withdrawing the pin (Z, and secured in said position by inserting the pin (Z, in the proper hole in plate F. And if the wheels at one side are lower than the ones at the opposite side, the bolster H, and bars h, h, are tilted and secured in the desired position by the racks J, serrated plates 0, and bar or clamp K. Thus it will be seen that the guides I, I, may always be adjusted in a vertical position however uneven the ground may be on which the machine rests.

Having thus described my invention what I claim as new and desire to secure by Let- J, J, serrated plates 0, and bar or clamp K,

ters Patent, is the Whole being arranged substantially as 10 The frames D, E, connected by pivots or and for the purpose set forth. joints 0 and retained in desired positions 1 T 5 by the perforated segment plate F, and pin CLUBIS LOVELESS' (Z, in combination with the bolster H, and WVitnesses: bars h, h, attached to the frame D, as shown W.

and secured in desired position by the racks G. W. C. TRAVER.
